调查了厚朴砍伐后其基部萌蘖培育成的再生植株(简称:萌蘖苗)与相同树龄实生苗的生长动态,比较了厚朴砍伐时的树龄以及树蔸盖土与不盖土等处理对萌蘖的影响.结果表明: 萌蘖苗生长速度比实生苗快,株高、地径、胸径都比实生苗增加幅度大,并随树龄增加其差别更大.萌蘖苗可提前3～5 a达到药材采收标准.并认为这一技术经济效益好,林地更新快,能减少水土流失,保护生态环境,是一项值得进一步研究和推广的经济林木可持续利用技术.%The growth status of plantlets regeneration from basal Magnolia officinalis Rehd. et Wils. after cutting down and the same tree-age of seedlings were investigated, furthermore, the influence on sprout shoots with different treatments, including the tree-age cut down, and earthed and unearthed up the roots were compared. The results showed that growth speeds and increasing ranges of height, ground diameter and breast diameter of sprout shoots were higher than those of seedlings, and the difference were much bigger with increasing tree-age. Sprout shoots were ahead of the harvesting time to 3～5 years. This technique has some advantages, such as good economic benefit, fast forest renewal, decreasing soil erosion, and protecting ecological environment, so it is worth to further study and extension.
